Abstract

A device and method for emitting output light utilizes Group IIB element Selenide-based phosphor material and/or Thiogallate-based phosphor material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the optical spectrum of the output light. Thus, the device and method can be used to produce white color light.
